Did needle-engine export Additive (Shader/Material) support?

Hey :wave: Overview of all exported materials is here:

Can you try using the UnityGLTF/PRBGraph or UnityGLTF/UnlitGraph and switch the blending mode to additive?

Do you have a screenshot of your scene and what visual you are going for? :slight_smile:

I tried setting the blending mode to additive in UnityGLTF/UnlitGraph, but the result still looks like alpha blending. What could be causing this issue?

Can you please screenshot your whole material in unity? (including what shader you are using)

Since on the second picture, it looks that the rays are opaque and not transparent at all.

Hi, the additive blend mode is not part of the glTF spec so it doesnt work out of the box right now. What you can do is create a little script that sets the blend mode to additive of your material in the awake method for example.

You can get the ParticleSystemRenderer with the getComponent call to modify the material (or assign the same material to your script)
